A Quasar Portrait Gallery

Quasars, or quasi-stellar objects, lie near the edge of the observable universe. They emit prodigious amounts of energy, visible across billions of light-years. Many astronomers believe a quasar's central engine is a giant black hole fueled by infalling gas, dust, and stars. This gallery of quasar portraits was captured by the Hubble Space Telescope.
